FILE-CLEANING TOOL.

Application filed February 24, 1925.

such as are used by metal Aworkers and other artisans, and particularly to means for cleaning files which have become filled with grease, dirt, soft metals, etc.

The lirst object of this invention is to provide an exceedingly simple and eflicient tool for cleaning tiles.

rlhe second object is to eliminate the waste usually occurring when a tile is discarded on account of being dirty instead of being actually dull. f

The third object is to provide an ineXpensive and highly efficient form of advertising novelty. n

rEhe fourth object is to conserve time on the part of mechanics by enablingl them to use a clean fle, which must necessarily out faster than a tile filled with foreign matter.

These results are attained in the manner set forth in the following speciiication as illustrated in the accompanying drawing, in which Figure 1 is a front elevation of the device of which Figure 2 is aplan and Figure 3 is a side elevation. Figure 4 is a vertical sec" tion taken along the line 4.-4; in Figure 1. Figure 5 is an enlarged longitudinal section through a portion of a file and the file-engaging portion of the device. Figure 6 is a vertical section taken along the line 6 6 in Figure 5.

Similar numbers of reference refer to the saine parts throughout the several views.

Referring in detail to the drawing, the device consists of a somewhat heartlshaped member 10 having relatively straight edges 11 and 12 and a V notch 13 formed therein. The portions 14 and 15 of the edges are preferably rounded. A groove 16 is completely formed around the edge of the device and terminates in a pair of holes 17 in the notch 13. rllhe member 10 is preferably made of wood or papiersmch, and in some cases is Serial No. 11,226.

provided with a printing surface on its flat side for the purpose of bearing advertising.

The edges 18k are preferably chainfered,

as indicated. Around the groove 16 is securely placed a round wire 19, preferably of a soft metal such as solder, whose ends 2() .are forced into the holes 1 7.

In Figures 5 and 6 are illust-rated a portion ofa file 21 whose teeth 22 are shown being cleansed of the foreign matter 23.-

'lhe operation of the device is as follows: It is held in one hand 'and moved along the cutting edges of the lile under a slight pressure, as indicated in Figures 5 and 6. The teeth 22 quickly cutting their way into the soft metal wire form a counterpart of themselves in the wire which scrapes out any foreign matter which may be lodged there, comn pletely cleaning the teeth.

If desired a straight-sided wire 19 (not shown) can be employed which will more effectively scrape out the foreign matter, the round one having been shown merely on account of the fact that round wire is more readily obtained than is one of a 'special cross section.

I am aware that le cards and similar devices have long been employed for the purpose of cleaning iiles, l therefore do not vclaim such devices broadly but I do intend to cover all such forms and modifications of this device as fall fairly within the appendf ed claims.

l claim:

l. The con'ibination of a. holder having' flat sides and a groove formed around the edge thereof; and a soft wire partially embedded in said groove.

2. The combination of a holder having` relatively straight lateral and lower edges and having a V-shaped recess in its upper edge and having a groove formed .in the edges thereof terminating `in holes .in said V-shaped recess; and a rsoft wire partially embedded in said groove surrounding said holder and haxfing its ends secured in said holes, a portion of said wire projecting beyond said holder throughout its entire length except that portion thereof which is within said holes.
